I really dont see why the weigth issue, take the cheapest ARF use the cheapest equipement on it and 99% of them will be under 5kg so? whats the problem??

also these rules limit the top end, maximum 5kg, max 2M, so nothing is telling you you cant fly with a .90 size airplane, in the lower clases (the case in this country) and I am sure is the same in the US, lets see basic, or sportman the guy flying a state of the art top F3A airplane is in advantage formo any other plane?? lets say a venusII or a focus 110 NO! same thing so?? is expensive because people want it to be expensive, everyone can fly with a cheaper model, but we want state or the art technology..
